Description
In this article, the special classification of logging machines and technologies of carrying out cleaning cutting is considered. The mathematical model of quantity of the damaged trees, remaining after cleaning cutting in coniferous plantings is described. The decision of optimization problem of quantity of damaged trees and productivity of logging machines at cleaning cutting is submitted. Possible decrease of quantity of damaged trees is shown, due to use of the automated choice of system of logging machines

AUTOMATIC CONTROL SYSTEM OF CHARACTERISTICS OF DEVICES OF MOVING ON THE AIR PILLOW
DescriptionMethods of jet pneumoautomatics with reference to devices of moving on an air pillow are considered. The local system constructed on the basis of methods of jet pneumoautomatics, for management of thickness of an air pillow is shown. In clause the opportunity of automatic removal of dusty air from a working zone of pneumotransport system is reflected. On the basis of hydro dynamical calculation parities for engineering calculations of values of

MODELS AND METHODS OF CONTROL SYSTEMS OF ECOLOGICAL SAFETY OF FOUNDRY MANUFACTURE
DescriptionThe given developments are devoted to modeling of control systems by ecological safety of foundry manufacture. In a working zone of foundry shops except for a dust the significant amount of polluting substances is allocated. The most unsuccessful sites from a position of allocation of a dust are chambers and lattices. The experimental analysis shows, that in structure of a dust the weight maintenance of fractions with a diameter up to 20 microns reaches 43,8 % on weight. The given dust is most dangerous to health of the working personnel and creates problems when clearing the air
